Direction:Looking due north, altitude about 75 degrees up from horizon. Weather: was about 75% clear with broken clouds, numerous chem trails about 70 degrees F.

Event: I noticed a white sphere traveling to the northwest at around 50-60 thousand feet. It traveled with a trajectory that a normal plane would have. There was no con trail left as it traveled. As it traveled another small white object (sphere) came/fell down verticall down from an old spread out chemtrail overhead and briefly followed the first object. It begain to do a cork screw maneuver behind the first object then turned back up vertically, keeping it's corkscrew trajectory back up into the cloud from which it orginally came from. The first object continued on as nothing had happened. I waited about 10 minutes to see if anything else might happen. None did.
